Multithreaded recording video 2 capture cards same time

is it possible to record 2 video and audio input sources with 2 instances of quicktime pro? I figure that a multi core computer would be able to do this. but not sure.
I would be capturing from a DVI/VGA source (no Audio) and a composite source with audio. I have both an Osprey capture card and a Datapath Capture card
Can Qucktime Pro do this with finess?

Some considerations beyond cpu power:
QTPro would not let me start two new recordings at the same time. However you could have another application that can record.
What resolution and frame rate is the dvi/vga? You could have a disk data limit if both resolution and frame rate are high. 640 x 480 @ 75 fps would require more than 70 MBps, for example.
If you want compression but your cards can't do hardware compression you could run out of cpu.

Recording Video and Audio at Same time with simultaneous sync

I want to record a keyboard performance into garageband and at the same time record the playing of that performance with my video camera. Then I want to create a movie using the music from garageband and the video from the camera. I was thinking that if I can sync the video and audio when I'm recording the session, then that part is taken care of. Or, maybe this is easier than I think it is?
Is there a way to do this so that I can use the garageband record performance and have it synced to the video on the camera?
I don't want to use the audio from the video camera because the performance that is captured in Garageband will be much better and I can do editing of the individual notes in GB.
In the end, I just want to make a movie and/or podcast of the performance.
I'm a newbie regarding this, but I did search the forums and couldn't find anything specific. Mostly it was about importing video into GB3 and then syncing new audio. I'll basically have audio and video from the same performance in two separate locations and I want to bring them together perfectly in Garageband.
Thanks for any help you can provide.

Okay. I got the video and audio all together. I told you I'd link to it when it was up.

There's also a copy of it at http://www.myspace.com/bonjimmy/
And as a quick side comment, even though I uploaded the same video to both YouTube and MySpace, the MySpace version is much better. YouTube must do something to the video after it's uploaded.
What I learned doing this project:
I recorded the video first (which gave me the sequencing of the piano performance) and then I dubbed the audio in later. However, there wasn't a good way to sync the video and the prerecorded piano, so there are some spots where the dubbed audio vocal isn't accurate to the video. I'm not sure what the pros do for this. I was hoping I'd remember how I sang for the video but when a couple weeks go by before re-doing the audio, it's about impossible. I tried, though.
I remember working with an old 4-track and smpte to a sequencer a long time ago. With the way it is now, it's pretty cool that you can record digitally and mix and match and everything falls together perfectly as long as you have a place to match the video and the audio. It's pretty cool.
What else???
Does anyone have suggestions that would have made it better? Also, if you have suggestions on my performance or whatever, I'd love comments, but you can do that on the linked page.
Thanks again for all your help. (The point of the video is because I'm thinking about getting back out there and doing some more playing... I'm looking for a band or something else interesting...)

Can Express 9 play and record multiple instruments at the same time?

I have logic express 9 and was told with my interface that I can play and record different instruments at the same time on Express 9. Is this true because I have spent a long time trying to figure out how.

Hi,
to record multiple Inputs at a time, open up the appropriate number of audio tracks. Now for each track, select the correct Input in the Channelstrip.
Now, ARM all these tracks for recording by clicking the little red R in the track header or channelstrip. Now if you hit record, all these tracks should record simultaneously their respective inputs.
All other existing tracks should playback while recording.

Play two video files at the same time.

I am trying to play two video files at the same time. I create two threads, each of which has its own frame, playing button, and builds its own graph to play the file. Now everything seems works except that when the first file is being played and I hit PLAY
to play the second file, the program plays the second file but the first one is paused; furthermore the control button has no response for the first one. Did I miss anything? Can anyone help me figure out the problem?
Best,
Fayin

You don't need separate threads for 2+ playback pipelines because the filters create worker threads internally and don't block execution on calling thread.
If you decide to keep separate threads, you will have to follow Michel's advice and have message pumps on those threads.
You can also have both files in the same graph, in which case you have perfect sync between them (both start playing together in sync), however you cannot pause/stop/run files separately.
The problem you described is most likely not a DirectShow problem and is rather about generic threading, COM or window messaging.

Recording 4 microphones at the same time to GarageBand?

I'm wanting to record 4 microphones at the same time to Garageband on the iPad (4th Gen) for a 4-person podcast I'll be working on. I'm wondering if there's an inexpensive solution ($275 and under) to do that.
I'd like to be able to record each mic to a different track so I can work on them in post. I'd also like to be able to attach a MIDI keyboard for stuff unrelated to the podcast itself.
So far, I've been looking at these devices which all seem to have their own caveats:
Alesis IO Hub (only two XLR inputs)
Alesis IO Mix (no USB)
Focusrite 18i8 (a little over the price I wanted to pay)
Everything else I've looked at is either more expensive or has too few XLR inputs. If anyone out there can lend their expertise and advice to what my options are that would be great.
Thanks much,
Ray

Well, you can, but it is pretty darn expensive and requires quite a bit of hardware.

How do I layer 2 video clips in the same time space/ playing side by side at the same time

I wish to add 2 views of the same subject side by side and playing at the same time. Is this A possible and B if so how do I add the second video clip into the same time space

What version of Premiere Elements are you using and on what computer operating system is it running?
This sounds like a split screen effect to me.
If so, one view on Video 1 and the other directly above that is the other view on Video 2.
Then crop each so that each occupies 1/2 the Edit area monitor screen.
(generalized since I do not know your program version, see effects Transform/Crop).
I wrote the following in 2011 for a Premiere Elements 8 user in another forum
Your basic tools to achieve your goal are Crop Video Effect and Horizontal Flip Video Effect.
Video ONE on video track 1.
Video TWO on video track 2, directly above Video ONE.
Highlight Video ONE on video track 1, Edit Mode/Effects/Video Effects/Transform/Crop, followed by adjusting the crop under Edit Effects (see bottom of Effects Panel) so that Video ONE occupies the left half of the screen.
Do the same for Video TWO on video track 2, Edit Mode/Effects/Video Effects/Transform/Crop etc. so that Video TWO occupies the right half of the screen. BUT end with Edit Mode/Effects/Video Effects/Transform/Horizontal Flip.
Highlight the video on either side to make adjusts in the Properties Palette and appropriate Panel (position, cropping, etc). But, remember that if you make changes in the "flipped" right side of the screen, Edit Effects/Crop Panel right option will be for left and left option will be for right.
You may or may not need the "flip" part of the effect.
Please review and consider. If I have misinterpreted your question, please let me know with details and I will rethink what you seek.
Thanks.

Help with recording 2 tracks at the same time

Basically I recently purchased an Audio Interface (BEHRINGER XENYX Q802 USB) and I'm having trouble recording multiple tracks at the same time while using it.
When I set up 2 MONO tracks in my DAW (one using input 1, the other using input 2) all that happens is that I get a recording of one mic over both tracks in my DAW.
This is probably a beginner post and I have looked it up on YouTube etc. but it just doesn't work for me... Maybe it has something to do with my Interface, but any help will be much appreciated.

Hi Pancenter,
Unfortunately I don't have the manual as I purchased it from a friend who failed to provide me with the Manual.
But thank you for answering as this was what I needed to do.
Many thanks
Olie.

Why cant I see BOTH video tracks at the same time?

I read all the manuals,I swear.
I make film collage and want to do multiple layer exposures of different clips.
So far I just have two video tracks-
Why cant I see BOTH video tracks at the same time,I mean each track will create another layer,or exposure that will both play back viewable simultaneously right ?Or would that be considered "layering"?
Does this have anything to do with the source vs. destination thing ?

FCE plays back video tracks in a "top-down" manner: that is what's on track 3 obscures what's on track 2 which obscures what's on track 1. You can control scale, position and opacity of each clip on each track so that you can get the layering you seem to be after.

How can i record 2 sources at the same time ?

Hello. I am a piano tutorial guy on youtube and am always trying to improve on the quality of my vids and so i go tan HD cam to record the videos in HD (canon HV30) . I also have this little app called "midikeys" and all it does is show a piano layout on the screen and the keys i press on my keyboard , light up on the on-screen keyboard. I want to know how to record my camera and that "midikeys" onscreen piano at the same time . i have a make shift workaround to doing this but it makes things a whole lot more complicated . i basically record the cam by imp[orting the live feed, and at teh same time a have quicklime recording the "midikeys" on the screen . is there a way to do it together ? thanks

Welcome Pianohero to the  iMovie boards..
.. is there a way to do it together ?
I dare to say: no way..
the hurdle to go is that 'keys visualizer' ..
as far as I understand, it does show 'live'.. and doesn't create quicktime movies, right?
so, you would need a 'screengrabber' tool as SnapZ or - better, but $$ - Screenflow.
such a screengrabber would create 'video files' of the action taking place on your monitor.
in a second step, you have to convert these files into something usefull in iMovie.
third step, you need an editing software which allows 'picture in picture' (=two video tracks). this an option in iMHD6 plus a plugin from geethree.com, or in iM09 or in FinalCutExpress ..
if anyone has a less complicated workflow..

Is there a way to see or play two video tracks at the same time?

I have video shot using two cameras at the same event. If I take the video and put it in a sequence, say video1 and video2, how can I watch both tracks at the same time so I can edit them? I tried using multi-camera monitor and have that show video1, while watching video2 in the right hand panel, but it doesn't work very well. By that, I mean the multi-camera monitor does not play at the same time. Instead, it stops, then when I play the other monitor it is still until I stop the other one. Then, it "catches up". If I play the multi-monitor, the other one is still until I stop the multi-cam monitor. So, anybody have a better solution that I can use where they both play at the same time?
BTW, my hardware is brand new and I have a 6-core i7-3930K processor with 16 GB of memory, so I don't believe the problem is with my hardware not being enough to run PPro 5.0 correctly.

Multiple Libraries for Video running at the same time on one PC

Hi Everyone -
I want to clarify this is for VIDEO files, not music for my 6 ATV's on the network.
Problem: I have well over 1000 VIDEOS in my iTunes Library, and I am wanting to have multiple libraries availible at the same time; not just whichever the computer has open.
We have several atv's on the network and I would like to take my video organization one step further; instead of scrolling forever in the atv menus for the video you want; I could make several libraries all availible at the same time.
Such as:
Kids Library
Workout Library
Parents Library
etc
This in turn would shrink the primary library and have less videos to sort by. I know how to create the Libraries, I just dont know how to have them all running at the same time.
Infastructure:
Windows 7 Ultimate with Drobo B800FS (16TB of storage) all connected to Cisco 3660 Gig switch with multiple atv's hardwired back.

iTunes can only open one library at a time. If you have multiple computers, or virtual machines, each could be serving a different library.

How do I record AND monitor at the same time?

I'm having trouble while trying to record from my XLR connected microphone. I have the mic going through a USB preamp and my speakers are outputting directly through my Power Mac. I cannot seem to be able to record at the same time I monitor. I can't playback my recordings without first changing the audio setting to Built in Audio from Mobile Preamp. I swear I could do this with Logic 7. Can't I have the monitor be going through the computer and the input going through my preamp at the same time? Thanks!
Appi

Logic can see two or more audio interfaces at once, but it has to be set up in the Audio midi set up program on your mac, as an aggregate device using your built in audio and your USB device. Then you can choose the aggregate device in your Logic>preferences>audio>driver. After you choose it, you should be able to access all inputs and outputs at once

How do i record 2 tracks at the same time.

i use a mixer to hook my mics into garageband, what i want to do is have 2 separate tracks and have them able to record at the same time. ive made separate tracks for each mic but i can only highlight one at a time to record so i need to figure out how i can have both tracks highlighted and giving me levels. if anyone can shed some light on this for me that would be great. i get the feel like theres a simple solution to this.

How to Slice Video, and Audio at same time

Hello Everyone.
When I click on Control K, it dose create a Slice in my Timeline, I want to create a Slice for my Audio as well, at the same time.
But every time I Slice a Video, and when I want to delete the Slice portion of the movie that I cut, the audio is still there, and I have to use the Razor Tool to select the cut portion under the Sliced movie.
Thanks
Simon.

Rod,
Through CS3, Ctrl+K worked on all Unlocked Tracks. With CS4, things changed a bit, as one could now Target multiple and even none contiguous Tracks. Ctrl+K still functions the same BUT now only affects Tracks that are Targeted, so no need for Locking them anymore. This has not changed with CS5.
Hope that this helps - it was changed as of CS4.
Hunt
PS - another workflow in CS3 and before, is to do the Crtl+K and then just ignore the Cut in some of the Clips, and just Alt+clicking on what you wish to remove, leaving the others alone. Though there is a Cut, one does not have to concern themselves with them, unless they wish to. Personally, I like the CS4 and later way of doing it - saves that Locking/Unlocking, or having to Alt+click to do things. However, I am a lazy sot.
PPS - Colin brings up a good point - how one has mapped THEIR keyboard shortcuts.

Need help recording three shows at the same time

I have the FiOS DVR, and have a problem this TV season. There are 3 shows that we watch that are on at the same time. if we are home that night, we can record two on the DVR and watch the other in another room. Not ideal, but we can handle it. But if we are out, we are hosed. I have an old series 1 Tivo that I would think I could factor in here....which I could timer record on a different TV. Any way to do it on my regular TV? Not sure how I could hook up the Tivo with the DVR and the rest of it.
Thanks!
Alan

I have a similar setup with a Replay.
You will need to get a Verizon Digital Adapter for $3.99 per Month and an IR Blaster for your Tivo.
Connect the Digital Adapter (DCT-700) to the FIOS Coax (May need to use a Splitter). Connect the Composite Out cables from the DCT-700 to the Tivo. Connect the IR Blaster from the Tivo to the front of the DCT-700. Configure the Tivo and tell it you have FIOS Cable and Digital Adapter. You may need to find the right codes to use to control the FIOS box from the Tivo.
Once you get it configured you will be able to tell the Tivo to record the 3rd program and it will switch the box to the channel and record it. If the box is near your other Verizon STBs you will need to hide it or cover the IR Sensor so that the remote for the main STB does not control the Digital Adapter.
As an added bonus you can connect the Coax Out from the DCT-700 to your Main TV if it has PIP and now you have a 2nd input source to make PIP work.
